A review of the article "Introducing percents in linear measurement to foster an understanding of rational-number operations" A critical reading

Teaching Children Mathematics; Feb 2003 Introducing percents in painsar measurement to foster an misgiving of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable poesy focuses on rules and memorization. Teachers often give students instructions such as, To stuff up fractions, first find a common denominator, therefore summarise only the numerators or To add and subtract decimal fraction numbers, line up the decimals, then do your calculations. However, Remembering and in good order carrying out these relatively simple rules can be precise difficult, however, when students do not have a good conceptionual introduction in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost daily because my teacher evaluate me to bonny accept what she was saying and to memorize. Interestingly, this article presents computation abilities in shrewd numbers that were developed by fourth club students who partici pated in a research bulge out on the learning of rational numbers (Moss and Case 1999). The goal of this on-going research project is to foster a flexible, interconnected intellect of the rational-number system. Students begin their investigations of rational numbers by learning to the highest degree percents in the consideration of linear measurement. The learning of fractions and decimals comes later and is grounded in students learning of percents. Although this attempt alters the traditional teaching sequence for rational numbers, it has many advantages for teenage students.

For example, by beginning with p ercents rather than fractions, educators ta! bularize the problem of students having to comparing or manipulate ratios with contrary denominators. This accepts children to distil on growing their own procedures for comparison and calculation, instead of essay to master a complex set of procedures that might count foreign to them. A irregular advantage of this instructional come on is that by beginning with percents, we allow children to make their first conversions among the different representations...
